Gain a deep, intuitive and technical understanding of practical options theory The main challenges in successful options trading are conceptual, not mathematical. Volatility: Practical Options Theory provides financial professionals, academics, students and others with an intuitive as well as technical understanding of both the basic and advanced ideas in options theory to a level that facilitates practical options trading. The approach taken in this book will prove particularly valuable to options traders and other practitioners tasked with making pricing and risk management decisions in an environment where time constraints mean that simplicity and intuition are of greater value than mathematical formalism. The most important areas of options theory, namely implied volatility, delta hedging, time value and the so-called options greeks are explored based on intuitive economic arguments alone before turning to formal models such as the seminal Black-Scholes-Merton model. The reader will understand how the model free approach and mathematical models are related to each other, their underlying theoretical assumptions and their implications to level that facilitates practical implementation. There are several excellent mathematical descriptions of options theory, but few focus on a translational approach to convert the theory into practice. This book emphasizes the translational aspect, while first building an intuitive, technical understanding that allows market makers, portfolio managers, investment managers, risk managers, and other traders to work more effectively within--and beyond--the bounds of everyday practice. Gain a deeper understanding of the assumptions underlying options theory Translate theoretical ideas into practice Develop a more accurate intuition for better time-constrained decision making This book allows its readers to gain more than a superficial understanding of the mechanisms at work in options markets. Volatility gives its readers the edge by providing a true bedrock foundation upon which practical knowledge becomes stronger. .Enllaç a la fitxa del llibre/Enlace a la ficha del libro

Clayton M. Christensen, the author of such business classics as The Innovator's Dilemma and the New York Times bestseller How Will You Measure Your Life, and co-authors Efosa Ojomo and Karen Dillon reveal why so many investments in economic development fail to generate sustainable prosperity, and offers a groundbreaking solution for true and lasting change. Global poverty is one of the world's most vexing problems. For decades, we've assumed smart, well-intentioned people will eventually be able to change the economic trajectory of poor countries. From education to healthcare, infrastructure to eradicating corruption, too many solutions rely on trial and error. Essentially, the plan is often to identify areas that need help, flood them with resources, and hope to see change over time. But hope is not an effective strategy. Clayton M. Christensen and his co-authors reveal a paradox at the heart of our approach to solving poverty. While noble, our current solutions are not producing consistent results, and in some cases, have exacerbated the problem. At least twenty countries that have received billions of dollars' worth of aid are poorer now. Applying the rigorous and theory-driven analysis he is known for, Christensen suggests a better way. The right kind of innovation not only builds companies-but also builds countries. The Prosperity Paradox identifies the limits of common economic development models, which tend to be top-down efforts, and offers a new framework for economic growth based on entrepreneurship and market-creating innovation. Christensen, Ojomo, and Dillon use successful examples from America's own economic development, including Ford, Eastman Kodak, and Singer Sewing Machines, and shows how similar models have worked in other regions such as Japan, South Korea, Nigeria, Rwanda, India, Argentina, and Mexico. The ideas in this book will help companies desperate for real, long-term growth see actual, sustainable progress where they've failed before. But The Prosperity Paradox is more than a business book; it is a call to action for anyone who wants a fresh take for making the world a better and more prosperous place.
